[0037] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0038] In the description of the present disclosure, it should be understood that the terms "upper", "lower", "top", "bottom", etc., indicating orientations or positional relationships, are defined based on the directions of the drawings shown in the accompanying drawings. They are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, and a specific orientation structure and operation. Therefore, they cannot be understood as limitations on the present disclosure.

[0039] In this disclosure, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another and do not have order or importance. In addition, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.

[0040] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed," "connected," "connected," and "installed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; and they may refer to direct connections or indirect connections via an intermediary. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.

[0041] like Figures 1 to 5 As shown, the present application provides a battery box 100, including a box body 10, a box cover 20 and a limiting component. The box body 10 includes a bottom plate 11 and a side plate 12. The bottom plate 11 and the side plate 12 enclose a storage space 13 for accommodating the battery body 200. The box cover 20 is connected to the box body 10 to close the upper opening of the storage space 13. The limiting component includes a first limiting plate 31 and a second limiting plate 32. The first limiting plate 31 is installed on the bottom plate 11 and is suitable for limiting the lower part of the battery body 100. The second limiting plate 32 is detachably connected in the storage space 13 and is suitable for limiting the upper part of the battery body 200.

[0042] Compared with the solution of filling the gap between the battery box and the battery body with rubber, in the present invention, the limiting component is installed inside the accommodating space 13 of the box body 10 through the above technical solution, and the limiting component is used to limit the position of the battery body 200 inside the battery box 100. While fixing the position of the battery body 200, it will not block the gap between the battery body 200 and the battery box 100, and can provide heat dissipation space for the battery 1000, so that the battery 1000 can have a better heat dissipation effect, which is beneficial to improving the heat dissipation performance of the battery 1000.

[0043] In the present disclosure, a storage space 13 is provided within the battery case 100 for accommodating the battery body 200. A limiting component is provided within the storage space 13, wherein a first limiting plate 31 can limit the lower portion of the battery body 200, and a second limiting plate 32 can limit the upper portion of the battery body 200. This secures the entire battery body 200 within the storage space 13, thereby achieving relative fixation between the battery body 200 and the battery case 100. Because the limiting component is provided as a plate, a gap exists between the plate and the case 10, preventing a completely sealed gap between the two. Consequently, a gap exists between the battery body 200 and the battery case 100 for heat dissipation from the battery body 200, thereby improving the heat dissipation performance of the battery 1000.

[0044] The second limiting plate 32 is detachably connected to the accommodating space 13, which facilitates the installation and removal of the battery body 200. For example, when the battery body 200 needs to be fixed by the second limiting plate 32, the second limiting plate 32 can be installed in the accommodating space 13. When the battery body 200 is installed or removed, the second limiting plate 32 can be removed and the battery body 200 can be installed or removed. This facilitates the installation and removal of the battery body 200.

[0045] In the present disclosure, a receiving space 13 is constructed between the bottom plate 11 and the side plate 12 for receiving the battery body 200 . The box cover 20 can close the upper portion of the receiving space 13 and can be used to protect the battery body 200 .

[0046] In some embodiments, a handle may be provided on the top of the box cover 20 to facilitate operators in installing and removing the box cover 20 .

[0047] In the present disclosure, the battery box 100 can be constructed in any suitable shape to accommodate various types of batteries 1000, and the present disclosure does not limit this.

[0048] In this disclosure, Figure 1 and Figure 4 As shown, the limiting component may further include a third limiting plate 33, which is mounted on the side plate 12 and adapted to abut against the side wall of the battery body 100. In this manner, the side wall of the battery body 200 may be limited.

[0049] In this disclosure, Figure 1 and Figure 4 As shown, multiple third limiting plates 33 can be provided, and the multiple third limiting plates 33 are evenly spaced along the height direction of the battery box 100, and the multiple third limiting plates 33 are interconnected by connecting rods 34. Such an arrangement can further enhance the stability of the side of the battery body 200.

[0050] In some embodiments of the present disclosure, the third limiting plate 33 can be set as a rectangular plate, one side of the rectangular plate is perpendicular to the inner side wall of the side plate 12, and the other side of the rectangular plate can abut on the battery body 200 to limit the side of the battery body 200, thereby further limiting the freedom of lateral movement of the battery body 200. Among them, the connecting rod 34 between the multiple rectangular plates can be set parallel to the inner side wall of the battery box 100 and perpendicular to the third limiting plate 33, so that the connecting rod 34 can easily connect adjacent third limiting plates 33. For example, Figure 4 As shown, the third limiting plates 33 are arranged in groups of three and are installed on the same side of the inner wall of the side plate 12 . A connecting rod 34 is installed between two adjacent third limiting plates 33 to form a side limit for the battery body 200 .

[0051] In this disclosure, Figure 1 As shown, the limiting component may further include a threaded rod 36 and a nut 37. A through hole 322 is provided on the second limiting plate 32. One end of the threaded rod 36 is connected to the third limiting plate 33. The threaded rod 36 is inserted into the through hole 322. The nut 37 is sleeved on the other end of the threaded rod 36 and pressed against the side of the second limiting plate 32 facing away from the third limiting plate 33. This arrangement facilitates installation of the second limiting plate 32 within the accommodating space 13. The threaded rod 36 and nut 37 are used to secure the second limiting plate 32, thereby ensuring that the second limiting plate 32 can secure the battery body 200.

[0052] In some embodiments of the present disclosure, the threaded rod 36 may be integrally formed with the connecting rod 34 , thereby improving the strength and stability of the entire rod body and further ensuring the stability of the connection of the second limiting plate 32 .

[0053] In this disclosure, Figure 5 As shown, the second limiting plate 32 may be provided with a clearance groove 321. The inner contour of the clearance groove 321 is adapted to fit within the outer contour of a portion of the upper portion of the battery body 100. A protective pad 35 is disposed within the clearance groove 321. The inner wall of the clearance groove 321 is adapted to abut against the battery body 100 via the protective pad 35. This arrangement can protect the upper portion of the battery body 200 and reduce friction damage between the upper portion of the battery body 200 and the second limiting plate 32.

[0054] The second limiting plate 32 can be configured as a single integral plate or as multiple plates, as long as the upper position of the battery body 200 can be fixed. In an embodiment where the second limiting plate 32 is configured as multiple plates, three second limiting plates 32 can be configured. A protective pad 35 is connected to the inner wall of the clearance groove 321. The protective pad 35 is configured as a rubber pad having a size matching the clearance groove 321. The second limiting plate 32 is provided with a through hole 322 for inserting the threaded rod 36. After the battery body 100 is stably placed on the inner box 14, the three second limiting plates 32 are sequentially installed on the upper part of the battery body 200, and the threaded rod 36 is inserted into the through hole 322 of the second limiting plate 32. The nut 37 is then used to sleeve the threaded rod 36 and rotate it to achieve the installation and fixation of the second limiting plate 32. The provision of the protective pad 35 can reduce the wear caused by the second limiting plate 32 when fixing the battery body 200, thereby improving the safety of the battery 1000.

[0055] In this disclosure, Figure 4 As shown, the first limiting plate 31 may include a fixed plate 311 and a bending plate 312 connected perpendicularly to each other, the fixed plate 311 is configured as a flat plate, the fixed plate 311 is connected to the bottom plate 11, and the bending plate 312 has a first limiting surface and a second limiting surface, the first limiting surface and the second limiting surface respectively abut against the side walls of the battery body 100 on different sides. Among them, the fixed plate 311 is configured as a flat plate, and the connection of the fixed plate 311 to the bottom plate 11 can increase the connection area between the first limiting plate 31 and the bottom plate 11, thereby improving the stability of the connection between the first limiting plate 31 and the bottom plate 11. The first limiting surface and the second limiting surface of the bending plate 312 can be adapted to the side surface of the lower position of the battery body 200, thereby ensuring that the lower part of the battery body 200 is limited in at least two directions, thereby ensuring that the position of the battery body 200 is fixed.

[0056] In an embodiment where the battery body 200 is a rectangular block, four first limiting plates 31 may be provided. The four first limiting plates 31 may be installed at the four corners of the bottom plate 11 by bolts to limit the four corner positions of the lower portion of the battery body 200 .

[0057] In this disclosure, Figure 1 As shown, the battery box 100 may also include a heat dissipation structure, which includes a fan 41 and a heat dissipation channel 42. The fan 41 is mounted on the inner side wall of the side panel 12, and the heat dissipation channel 42 is provided on the side panel 12 and connects the fan 41 with the external environment of the battery box 100. This arrangement can improve the air circulation inside the battery box 100, thereby increasing the heat exchange rate and further improving the overall heat dissipation effect of the battery 1000.

[0058] In some embodiments, the battery box 100 may also include a dustproof net 50, which is arranged on the inner wall of the side panel 12. In order to avoid interference with the internal structure of the battery box 100, the dustproof net 50 can be arranged between some adjacent third limiting plates 33 to absorb dust, debris and other impurities inside the battery box 100, prevent impurities from being adsorbed on the battery body 200, and thereby reduce damage to the battery body 200.

[0059] In this disclosure, Figure 1 As shown, the battery box 100 may further include side heat sinks 43 connected to the outer sidewalls of the box body 10. This arrangement can increase the contact area between the outside of the battery box 100 and the atmosphere, improve heat exchange between the inside and outside of the battery box 100, and further improve the heat dissipation effect of the battery 1000.

[0060] In this disclosure, Figure 1 As shown, the battery box 100 may further include a support member 60 and a bottom heat sink 44. The support member 60 is connected to the underside of the bottom plate 11 to support the battery box 100. The bottom heat sink 44 is connected to the bottom plate 11 and is disposed through the bottom plate 11. In this way, the support member 60 supports the battery box 100, allowing heat dissipation space to be created at the bottom of the battery box 100. The bottom heat sink 44 is disposed on the bottom plate 11 and penetrates the bottom plate 11, adding a heat dissipation structure to the bottom of the battery box 100, thereby achieving better heat dissipation at the bottom of the battery box 100 and improving the heat dissipation performance of the battery 1000.

[0061] In some embodiments, the support member 60 includes a support frame 61 and a support plate 62. The support frame 61 is configured as two flat plates connected vertically to each other, one of which is vertically connected to the lower side of the base plate 11, and the other is supported on the installation position of the battery box 100 (for example, the ground). In this way, the stability of the support frame 61 can be improved.

[0062] According to a second aspect of the present disclosure, a storage battery 1000 is provided, including a battery body 200 and the aforementioned battery box 100 , wherein the battery body 200 is installed in the battery box 100 .

[0063] In the present disclosure, the box body 10 may include an inner box body 14 and an outer box body 15 that are connected to each other. A connecting frame 16 for connecting to the box cover 20 is provided on the upper end of the outer box body 15. A sealing member 17 is provided between the connecting frame 16 and the box cover 20. The provision of the sealing member 17 can improve the sealing performance of the connection between the box cover 20 and the connecting frame 16, so that the upper part of the box body 10 can be sealed. Figure 3 As shown, the connecting frame 16 , the sealing member 17 and the box cover 20 are all provided with connecting holes for inserting bolts, and the box cover 20 can be connected to the mounting frame and the sealing member 17 by bolts.

[0064] The specific use of the battery 1000 is as follows: after opening the box cover 20, the battery body 200 is stably placed inside the inner box 14. The first limiting plate 31 is used to limit and fix the lower part of the battery body 200. The three second limiting plates 32 are placed on the upper part of the battery body 200 in sequence, and the threaded rod 36 is inserted into the through hole 322 of the second limiting plate 32. The nut 37 is then used to sleeve the threaded rod 36 and rotate it to achieve the installation and fixation of the second limiting plate 32. The protective pad 35 is provided to prevent the second limiting plate 32 from causing wear when fixing the battery body 200, thereby improving the safety of the battery body 200. The third limiting plate 33 is provided to limit the side wall of the battery body 200 and is relatively fixed to the threaded rod 36, which can improve the stability of the third limiting plate 33 and the second limiting plate 32. After the battery body 200 is installed, the fan 41 is started. The fan 41 works and is used to accelerate the circulation of gas inside the inner box 14 (i.e., the accommodating space 13), thereby achieving cooling of the battery body 200. By setting the bottom heat sink 44, and then by heat dissipation treatment of the inner box 14, the heat dissipation effect of the battery 1000 is achieved. By setting the support member 60, the battery box 100 can be supported to ensure heat dissipation at the bottom of the battery box 100.

However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0066] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction, and the present disclosure will not further explain various possible combinations.

[0067] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
